The rise of back contact cell architecture

Sometimes, progress involves looking backwards. In this case, a return to back contact solar cell architecture has resulted in improved efficiencies and reductions in cost.

Evaluating the performance of mono- and poly-Si solar PV technologies in Eastern India

Researchers from the SRM Institute of Science and Technology, Ghaziabad, have studied the performance of monocrystalline silicon (mono-Si) and polycrystalline silicon (poly-Si) technologies in the tropical wet region of eastern India. The results showed that the yield outcome with mono-Si PV was around 12% higher and the losses around 32% lower than poly-Si PV.

Solar modules: The latest in technologies and applications

The evolution of solar technology in India isn’t solely focused on technical advancements but also on making solar energy more affordable and accessible to a wider demographic.
